OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 433,244, dated. July29, 1890.

Application filed May 10, 1889. Renewed June 30,1890, Serial No. 357,184(No model.)

To all whom it may concern.-

Be it known that I, MATHrAs JOLLY, a resident of Troy, in the county ofRensselaer and State of New York, have invented certain new and usefulImprovements in Oil-Cans; and I do hereby declare that the following isa full, clear, and exact description of the invention, that will enableothers skilled in the art to which it appertains to make and use thesame, referencebcinghad to the accompanyingdrawings, and to the lettersof reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to improvements in oilcans and it con sists in thenovel construction and combination of parts hereinafter described, andpointed out in the claim.

Figure 1 of the drawings is a central vertical section of my improvedcan and the enlarged pump-chamber, the pump-tubes being shown inelevation. Fig. 2 is a central vertical section of the pump-tubes. Fig.3 is a top plan view of the perforated drip-guard detached from theinner side of the perforated can-cover. Fig. i is a horizontal sect-ionFig. 5 is a side elevation of the pump-plunger detached from thepump-cylinder. Fig. 6 is a central cross-section of the two disksforming the piston,riveted together and detached from the other parts.Fig. '7 is a central vertical section, on an enlarged scale, of thepistonhead, guide, concaved valve, valve'stem, and

piston stop fixed thereon detached from the tubes.

The can A is shown provided with a depression or sink A in its cover,which has a central drip-openin g A and with a pump located near theperiphery on one side of the can, havin g a nozzle A projecting over thesink A. The nozzle is secured to the enlarged chamber-case B, and thecase is fixed upon the pump'cylinder 13 which is rotary in and movablelongitudinally of the tube 13 the tube extending in a fixed positionfrom the top to the bottom of the can, as shown in Fig. 1.

\Vhen it is desired to fill a lamp, the nozzle is lifted until the lampcan be deposited in the sink upon the can-top. The nozzle is then lowered and swung around until it enters the filling-inlet of the lamp,after which the pump is operated to fill the lamp in substantially themanner heretofore employed an d well known. The central perforation Apermits any overflow to pass down through and drip into the can. Duringthe transportation of the filled can so perforated the oil islikely tobe forced violently out of the perforation unless the same is protected.I provide as such protection a small cap or drip-guard A, which isprovided with small perforations A in the vertical walls of the guard,and may have an attaching-flange A, by which it is soldered to the innersurface of the can-cover. as shown in Fig. 1.

The pump piston, which is adapted to slide in the cylinder 13 and uponthe valve-stem P, has a novel form of construction, is cheaplyconstructed, and durable. The piston is pro- 'vided with a centralaperture P, made considerably larger than the valve-stem, to receivesuch stem and at the same time permit of the passage of the desiredamount of fluid. I have shown the piston made of two centrally-perforated disks 1 and P secured to each other by a hollow rivet P, passedthrough their central perforations, and of a sleeve or piston-guide Padapted to slide upon the valvestem. The piston-guide is secured to thepiston-head by soldering it to the small upper disk, which may be madeof copper, tin, or other material to which solder will readily adhere,while the lower disk P which is required to do the work of a piston, maybe made of cast-iron or other metal. I have shown the guide secured tothe upper disk by a series of downwardlyprojecting teeth P, which can beeasily soldered to disk P Any desired number of teeth or arms, as threein the form of a tripod, may be employed.

The valve-stem is provided with the valve P fixed upon its lower end.This valve is preferably made of a concaved piece of sheet metal adaptedto inelose the rivet P and be seated upon the lower side of the disk toclose the central piston-aperture. The stem is also provided with a stopP fixed thereon, and at its upper end with an operating-handle P", alsowith the stops P and P hen the too stem is given aVertically-rcciprocating moing the downward movement of the piston bythe check-valve P in the bottom of the cylin- (ler, which may be anyknown form of checkvalve. The stops P and P limit the movements of thevalve-stem to short strokes, making it well nigh impossible for theoperator to pump the fluid into the chamber B faster than it will runfrom the nozzle, thereby preventing its running over the top through thestem-aperture. At the same time the operator can easily pump fast enoughto keep the chamber filled above the nozzle-outlet, thereby producing acomparatively steady stream of the fluid therefrom.

O is a packing-box secured to the fixed tube 13 This box is filled withpacking O, forming a tight joint around the vertically-reciprocatingcylinder B The box is screw-threaded and adapted to receive thecorrespondinglythreaded cap 0 I do not claim any invention in thedripopening and guard.

WVhat I claim as new, and desire to secure by Letters Patent, is

The combination, in a fluid-can pump, with a concaved valve fixed uponthe end of a reciprocatory stem, of a centrally-perforated piston-headformed of two centrally-perforated disks, a hollow rivet inserted insuch central perforations to connect the disks with each other and forma central slideway for the valve-stem reciprocatory therein, a piston-45 guide secured to one of such disks and provided with a centralslideway for the stem, and a stop P fixed upon the stem, substantiallyas described.

In testimony whereof I have hereunto set 50 my hand this 7th day of May,1889.

MATHIAS JOLLY.
